Klein Tools 53404 Ship Auger Bit 7/8 Inch

Product Description

The KLEIN TOOLS 53404 is a 7/8-inch ship auger bit designed for boring through wood framing, lumber, and structural members. Ship auger bits use a single-twist flute design that clears chips efficiently during deep drilling operations, reducing bit binding and heat buildup. Electricians and plumbers rely on this bit style when running conduit or pipe through floor joists, wall plates, and rough framing. The 53404 is a hand-tool-category bit suited for use with a heavy-duty corded drill or right-angle drill motor common on job sites.

This bit is primarily used in residential and light commercial rough-in work where 7/8-inch clearance holes are required through wood structural members. Typical applications include drilling through top and bottom plates for wire or pipe routing, and boring through wood beams or joists. The ship auger profile is well suited for deep-hole applications where standard spade or Forstner bits lose efficiency.

Key Features

• 7/8-inch cutting diameter for standard rough-in clearance holes
• Single-twist ship auger flute design promotes efficient chip ejection in deep holes
• Suitable for use in corded drills and right-angle drill motors
• Compact enough for tight framing cavities common in rough-in electrical and plumbing work

Compatibility

Designed as a standard ship auger bit for use with corded drills and right-angle drill drivers accepting standard round or hex auger bit shanks.

Installation Notes

This bit is installed and operated by licensed electricians, plumbers, and general contractors during rough-in framing stages. Always verify the drilling path is clear of live wires, pipes, or structural fasteners before boring. Secure the workpiece before drilling and use a drill with adequate torque for the material thickness. Follow applicable NEC or IPC clearance requirements when routing conductors or pipe through structural members.
